This invention relates to bottle fillers and cappers, and more particularly t a combined filler and capper. l l Y Among the objects of this invention is to provide means `for filling and venting bottles prevents the liquid from contacting the shell.

Other objects and advantages will appear v vas the description progresses.

In this speciiication and the accompanying drawing the invention is disclosed in its preferred form. But it is to be understood that it is not limited to this form because it may be embodied in other forms. It is also to be understood that in and by the claims vfollowing the description it is desired to cover the invention in whatsoever form it may be embodied.

In the one sheet of drawing:

. Fig. 1 is a vertical section of a. combined filler and capper constructed in accordance with this invention.

Fig. 2 is a fragmentary similar view of the same showing the filler in position on the mouth of a bottle.

Fig. 3 is a similar view after the capping operation is completed. v

In detail the construction illustrated in the drawing, referring to Fig. 1, comprises the outer shell 1, having the chamfered opening 2 at the bottom. Its upper portion or head 3 has a. threaded central opening therethrough into the opening 2. There is an intermediate shoulder 4 formed within the opening 2 below the underside of the head 3.

The vent opening 6 is formed laterally through the head 3. The filler opening 7 is formed laterally in the shell below the head 3. The tubes 8 and 9 lare fixed in the vent and iller openings and are telescoped within the nipples 8 and 9 to which are attached the rubber tubes 10 and 11, respectively.

i The valve 12`has theV` stem 13, the upper end of whichisenlargedto Aforma shoulder 14 and threadedtoeng'age the threaded center hole in the head 3. It has a lower reduced 'n portion above' the ltapered valve 12.' 55 The valve block 15 slides freely within they opening`2 and bottoms against' the shoulder et.y The cylindrical resilient rubber `sleeve. 18 seats on the valve block 15 within the lange- 19 and expands against the,v underside' 5 of the head 3.

The 'valve f is provided` an annular f notch inits outer edge to receive the yielding rulober7 guide and gas-liet 20 slidable within theopening 2. d

The block 15 is centrally bored at '17 -to a greater diameter thanthe reducedportion 13 'of the valve stem 13;; f

The block 15, the gasket' 20, andthe resil' ient sleeve 18'are assembled'on the valvestem 70 13'befo'reit is screwed'into thehead 3. The

. expansion of the resilient sleeve 18keepsn the vvalve block 15 'normally seated against the valve12.i"` The plunger 21 of the conventional capping machine has the vf threaded stud 22 screwed into the center opening in the head 3. The invention operates substantially as follows: f I `v The'bottlei's set on'theA baseoif the capper, not shown. The neclr'23 extends upinto the openingf2, wherein itiscentered by thebevelededge 24 or the gasket 20. fThe plunger 21 is then depressed, which forces `the gasket tightly againstthe outer edge 'of the mouth of the bottle.'y

Furtherfpress'ure vkupon'the plunger 21 lifts the valve block 15 against the vtension of the resilient sleeve 18, unseating the valve 12.

VThe liquid flows through 611e tube 11 and 79@ hole 25 in the sleeve'18, through the bore 17, and past the Valve 12.- y The flare of the valve 12 directs the liquid against the sides of the `neck 23, ldown which it flows, filling the bottle.' The air impounded in the bottle escapesupward through the center of the neck Yand through the center. opening26 in the valve stem and out through the tube-1Q. 1 Y

It is a fact that certainvfoaming beverages,

Vif poured against the inside of the bottle,

will not foam in bottle filling and Will not regurgitate if the impounded air can freely escape centrally.

If the bottle is to be filled by'siphoning through the tube 11, the siphon is readily started by suction on the` tubelO. The flow from the tube 11 cannot rise to Vthe tube 1.0 but descends into the bottle. The suction may be applied by the operator applying his mouth to a convenient length ofthe tube l0, or bymeans of an exhaust bulb applied in the tube length 11.

When the bottle is lilled the pressure on the plunger 2l is released, which permits 'the .valve block 15, to descend, closing thevalve 1.2. The liowthrough the ,tubell may also be stopped by a suitable pinch or other valve in the tubev 11.

A crown cap 27 is then placed over the mouth of the bottle. The plunger 21 is then depressed, which forces the valve block 15 down against the top of thecap, carrying it down against the top of the bottle. Simul- 4 Vtaneously, thefend of .the valve 12 descends and depresses the center of the cap 27, to cause it to sea-t concentrically on the rim of the mouth ofthe bottle, insuring a perfect i'it of. the asket 28,hermetically sealing the botblock and said head; and a gasket on saidA block slidably engaging said shell, and adapted to engage the mouth of a bottle inserted in said shell.

4. A bottle filler and capper, comprising a shell having a closed head and a chamfered o rening adapted whenorced thereon toclinc a bottle cap and having a filler inlet therein and a vent therefrom; a valve having 'al yhollow stem fixed in said head and open toL said vent; avalveblock slidable in said shell, and a resilient sleeve interposed between said block and said head and encircling the interiorv of said shell.

'5. A bottle filler comprising a shell having t'le.V ee Fig. 3.) vThe crown cap-is fixed in the usual manner by the opening 2, which contracts the iiuted skirt of thek cap under the bead forming the top of the bottle. The

plunger 2l. is again raised and theoperation l of filling and capping is complete.

While theattachment othis device tothe conventional capper plunger` is desirable, it is obvious that either pressure means or pounding on the head 3 would accomplish the capping operation.

Having thus described this invention, what I claim anddesire to secure by LettersPat ent is:

1. A bottle filler and capper comprising .a shell having a closed head and a chamfered opening Yadapted when forced thereon to crimp a bottle cap and having a filler inlet therein and a vent therefrom; and al valve withinsaid shell below said inlet'.

2. A bottle filler and capper comprising a shell having a closed head and a chamered opening adapted when forcedfthereonV to crimp a bottle cap and having a lfiller inlet therein and a vent therefrom; a valve having a hollow stem Xed in said head andopen to said vent; and a valve block slidably sealed in said shell and engaging said valve.

3. A bottle liller and cappelcomprising a shell having a closed head and a chamfered opening adapted when forced thereon to crimp a bottle cap and having a iller inlet therein and a vent therefrom; a valve having a hollow stem fixed in said head and open to said vent; a valve block slidable in ksaidshell; a. resilient sleeve interposed betweenV said
